HORN FOR AUTOMOBILES, MOTORCYCLES, AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 7, 1917.

To all whom it may concern;

Be it known that I, RAY H. MANSON, a citizen of the United States, residing in Elyria, in the county of Lorainand State of Ohio, have invented certain new and useful Improvements in Horns for Automobiles, Motor-Cycles, and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it appertains to make and use the same.

.My invention relates to signaling devices for automobiles, motor cycles and the like, though it is adapted for other uses and may in fact be used anywhere it is desired to use an audible signal.

In the use of high speed motor vehicles, it is necessary to employ a warning device to advise of the approach of the vehicle. My invention relates to such devices, and more particularly to an electrical horn or signaling device operated by an electric current. I aim to improve devices of this character, producing a horn cheaper to build, more substantial in construction, more simple to build, to inspect, to adjust and to operate and to produce a loud, clear signal.

Other objects of the invention and the invention itself will be better understood from a reference to ,.the particular embodiment illustrated in the drawing.

Figure 1 is an end elevation of an em- ,bodiment of my invention with the cover removed.

Fig. 2 is a side elevation with the cover removed.

Fig. 3 is a section through the embodiment of my invention taken at rightv angles to the view shown in Fig. 2. 7

Referring now to the drawing and to the particular embodiment of my invention illustrated therein, I show at 1 a frame member. As illustrated in the drawing, this member consists of a flat member with an opening 2 in the center part thereof. The edges of the opening may be slightly elevated, as shown at 3, giving the part of the frame member adjacent the opening a slightly dished appearance. An arm 4 is connected to the horn, preferably to the frame member and may be inte ral therewith, as shown.

The horn may e connected to a vehicle or other object by means of the arm member 4. This member is here shown as a flat arm, the

plane of which is substantially perpendicular to the long axis of the horn. A sound producing device, such as a vibratile diaphragm, 5, is supported from the frame and is here shown clamped between the chamber 1 and a front casing member 6, which is provided with an opening 7 for the egress of sound waves. A resonator 8 may be connected to this opening to transmit the waves. 1

Means for actuating the diaphragm are provided, here shown as including electromagnetic means 9, adapted to be connected in a circuit. At 10 I show an armature for the electromagnetic means, adapted to be moved thereby to strike an anvil 11, which transmits the motion from the armature to the diaphragm 5. The armature is connected by a leaf spring 12 to the member 14 and preferably to a lip 13 thereon, whichis supported from the frame. In the form shown the lip 13 is integral with the pedestal member, being folded backward, leaving an opening 15 in the pedestal member. Likewise, in the form shown, the pedestal member 14 is integral with a base member 16, which is mounted upon the frame member 1 inany suitable manner and fastened thereto by any suitable means, such as screws 17 It will be seen that when the screws are removed, the magnet and all its associate parts may be removed from the frame member.

Electric terminals 18 are mountedupon the pedestal member 14c and conductors 20 and 21 led thereto. These terminals are adapted to be connected to the terminals of an electric circuit for the magnet. An elec: tric switch adapted to control the circuit of the electromagnet and including a pair of contacts 23 and 24 mounted upon the leaf springs 25 and 26 may likewise be supported from the lip 13. One end of the spring 26 is supported by an insulating bushing 27 from the armature 10. The spring members are insulate from' each other by insulating bushings 28 and connected together by an insulating bushing 29. The contact springs, the armature spring and the armature and bushings 28 and 29 constitute a unitary structure which is connected to the lip :13 by some suitable means, such as a screw 30. This unitary structure may be removed for purposes of inspection and adjustment.

A second lip 31 is supported from the pedestal member and is here shown integral therewith, and formed by folding over the top of the pedestal member. Adjusting means, such as an adjustable screw 32 for the casing being clamped between the nuts and the edge of the frame piece 1 in a manner well understood.

The pedestal member is here shown as a fiat member made from a piece of sheet metal, the plane of which is perpendicular to the plane of the arm 4, so that when the horn is mounted upon a vehicle with the arm 4 extending horizontally in a vertical plane, which is generally the case, the pedestal member 14 will likewise be in a vertical plane, so that the jarring of the vehicle will not have the deleterious effect upon the sheet metal that might result from a constant jarring and slight bending of the metal, were the horn mounted so that the pedestal 14 were in a horizontal plane.

I have illustrated this particular embodiment of my invention, not that I desire to be limited to the details thereof, but simply for the purpose of illustrating the invention.

I claim 1. In an automobile horn, the combination of a frame plate member, a front casing member, a vibratile diaphragm between said members, a base plate member, a pedestal member on said base plate, means for actuating said diaphragm mounted on said base plate member, a lip member on said pedestal member, an armature for said actuating means supported from said lip member, a second lip member on-said pedestal, and an electric switch for controlling the actuating means, said switch consisting of two contacts supported from one of said lip members.
